Experimental Investigations for Modelling Hardness of ABS Replica Based Investment Castings

摘要

abstract_textpIn the present work investigations have been made to macro model the hardness of acrylonitrile butadiene styrene replica based investment casting (IC) of low melting alloys (non-ferrous) by parametric optimization of the process parameters for job/batch type production. The study started with selection of the component/benchmark of industrial applications with an idea of improvement in hardness of the cast components. The input parameters of the study are: part orientation in fused deposition modelling, number of slurry coating layers in IC, slurry coating layer combinations in IC and type of material (metal/alloy) in IC. The study highlights that at horizontal (0 degrees) orientation of the component; number of slurry coating layers contributes 38.16% and type of metal contributes 59.82%, whereas slurry coating layer combination contribution is very less in the present case study. Final results are supported with cooling curves and microstructure analysis./p/abstract_text
